Answer 1

We have that

x - 3y = 12 and -x + y = 4

We add the 2 equations together

x - 3y + (-x + y) = 16

-> -2y = 16

-> y = -8 (1)

We plug y = -8 into -x + y =4

-> -x - 8 = 4

-> -x = 12

-> x = - 12 (2)

From (1) and (2) we could conclude that the answer is B

Explain why |−3| + |9| represents the distance between the points (−3Explain why |−3| + |9| represents the distance between the points (−3, −5) and (9, −5)., −5) and (9, −5).

Answers

Answer:

Here we need to use:

[tex]\sqrt{x^2} = |x|[/tex]

The distance between two points (x₁, y₁) and (x₂, y₂) is given by:

[tex]D = \sqrt{(x_1 - x_2)^2 + (y_1 - y_2)^2}[/tex]

Then the distance between:

(-3, -5) and (9, -5) is just:

[tex]D = \sqrt{(-3 - 9)^2 - (-5 - (-5))^2} \\\\D = \sqrt{(-3 - 9)^2} = |-3 - 9|[/tex]

because both numbers inside the absolute value, we can rewrite it as:

|-3 - 9| = |-3| + |-9| = |-3| + |9| = 12

So, by finding the distance between  (−3, −5) and (9, −5), we got the given expression, in this way we prove that the given expression represents the distance between these points.

Answer:

under

Step-by-step explanation:

The points are on a horizontal line, parallel to the x-axis. The absolute value of −3 represents the distance from (−3, −5) to the y-axis, and the absolute value of 9 represents the distance from the y-axis to (9, −5).

Find the slope between the points (−3,−5) and (10,-5)

0

Step-by-step explanation:

[tex] m = \dfrac{y_2 - y_1}{x_2 - x_1} [/tex]

[tex] m = \dfrac{-5 - (-5)}{-3 - 10} [/tex]

[tex] m = \dfrac{0}{-13} [/tex]

from -3 to 10 are 13 steps to the right and from -5 to -5 0 steps up or down.

devide the steps up by the steps to the right

0 / 13 = 0

in this case it's obvious, but I hope you see the method how to do this. you would normally get a more interesting fraction as a slope.

In right ΔDEF, DF = 20, m∠ F = 90˚, EF = 17. Which of the following is true? Does option 5 apply

Answers

Answer:

Step-by-step explanation:

From the picture attached,

ΔDEF is a right triangle with two sides,

EF = 17 units

DF = 20 units

By applying Pythagoras theorem in the given triangle,

DE² = DF² + EF²

(20)² = DF² + (17)²

DF² = 400 - 289

DF = √111

Trigonometric ratios for the ∠F,

sin(F) = [tex]\frac{\text{Opposite side}}{\text{Hypotenuse}}[/tex]

[tex]\text{sin}F=\frac{\sqrt{111}}{20}[/tex]

[tex]\text{cosF}=\frac{\text{Adjacent side}}{\text{Hypotenuse}}[/tex]

[tex]\text{cos}F=\frac{17}{20}[/tex]

[tex]\text{tan}F=\frac{\text{Opposite side}}{\text{Adjacent side}}[/tex]

[tex]\text{tan}F=\frac{\sqrt{111}}{17}[/tex]

Answers

Answer:

Step-by-step explanation:

If cost price (CP) is greater than selling price (SP) , then the item is sold for loss.

Loss = CP - SP

Loss% = [tex]\frac{loss}{CP}*100[/tex]

If SP is greater than Cp, then the item is sold for a profit.

Profit =SP -CP

Gain % = [tex]\frac{gain}{CP}*100[/tex]

a)  CP = $50    ; SP = $30   ; CP > SP,  loss

Loss = 50 - 30 = $ 20

Loss % = [tex]\frac{20}{50}*100=20*2[/tex]

            = 40% loss

b) CP = £ 5000 ; SP = £6250  ; SP > CP ,  Profit

Profit = 6250 - 5000 = £ 1250

Profit % = [tex]\frac{1250}{5000}*100=25[/tex]

What is the slope of the line? What is the y-intercept of the line? y = 5/4x - 3

Answers

Answer:

m = 5/4

y intercept = -3

Step-by-step explanation:

The given equation of the line is ,

[tex]\implies y = \dfrac{5}{4}x -3[/tex]

We know that the Standard equation of Slope Intercept Form of the line is,

[tex]\implies y = mx + c[/tex]

Where ,

m is slope c is y intercept

On comparing to the Standard form of the line we get ,

[tex]\implies Slope = \dfrac{5}{4}\\[/tex]

[tex]\implies y - intercept= -3 [/tex]

general slope intercept form of a straight line is, y = mx + c

Slope of the line (m) = 5/4,

y-intercept of the line if when x=0 i.e.

y = 5/4x - 3

y = 5/4×0 - 3

y = -3

the angle of elevation of the top of a tower from a point 42 metres away from it's base on level ground is 26 degrees. find the height of the tower.

Answers

Answer:

20.485 Meters

Step-by-step explanation:

So first you wanna draw a diagram.  Start with the tower, then on the ground to the left (or right) draw a point.  The point will be labeled as 42 m away from the tower.  Now draw a line from that point to the top of the tower.  This makes your triangle, and that angle you just drew that touches the point is 26 degrees.

Now, since you have a right triangle you can use trig.  You know an angle and a side.  Specifically, relative to the 26 degree angle you know the adjacent angle and want the opposite, which is the tower.  So opposite and adjacent is tangent.  So you set up tan(26) = o/42 where o is the opposite side.  

So solving you get o = 20.485 meters

It is a serious question that requires a serious answer. One could present many answers as to why undertaking a robust space program is necessary, including everything related to jobs, education, technology development, and national security. In an ideal world, however, one answer is sufficient: we should undertake it for the most basic of reasonsfor our self-preservation as a creative, as opposed to a stagnating, society. The concept of space exploration is deeply rooted in our historical context. Exploration has always been part of the American character. The intangible desire to explore and challenge the boundaries of what we know and where we have been has provided benefits to American society for centuries. For example, the exploration of the American West during the 19th century is a prime example of American exploration that led to the advancement of society. More land was found on the western frontier for settlement and new resources were discovered for use, leading to the nation's growth. Some have argued that many of the distinctive characteristics that make up American society, including inventiveness, inquisitiveness, and individualism, derived from the existence of a frontier. Although the western frontier closed around 1890, Americans later found a new frontier where that same curiosity translated to space exploration. Space as a new frontier has always been a driver of the U.S. space programs. As H. G. Wells said many years ago, "Human history becomes more and more a race between education and catastrophe." We are still in that race today, and surely an international cooperative venture into space strikes a blow against catastrophe and leads to a victory for civilization. Great things were achieved in the past in the name of competition, including the Apollo program, which would never have happened without Cold War competition. The Space Race between the Soviet Union and the U.S. led to the development of programs devoted to scientific research and inventions. Specifically, after the Soviet Union successfully launched Sputnik I, the world's first artificial satellite, America responded by developing and launching a satellite known as Explorer I. It now remains to be seen whether great things may be done in the name of international cooperation. If history has taught us anything, we must look to the future with the goal of preserving a culture that embraces endless possibilities in the spirit of both science and exploration. As we have seen in the past, exploration of the unknown leads to advancements and improvements that are beneficial to society.
